Maths Methods (Exam 2): Discussion, Questions & Potential Solutions

p> 1/n.        P=x/n.     Therefore x>1

Compared to yesterday's exam - yes, SO much more doable. Probably landed at least 10% higher than it too. Kind of surprised that there wasn't a question like the Ferris Wheel one from last year - but that's fortunate.
Also, how did anyone approach that sampling question? The one where you had to find the least value of n. (It's kind of cheesy that they had named population as adults from Mathsville and Statsville, or whatever they're called)
But that last page, woaAAHH, I grabbed answers out of no where. (What was the area between inverse of g, x-axis and that other line? I got 1 square unit, wtf)

I also got 1 square unit lol fairly certain it's wrong though

No, but NOTHING REALLY MATTERS  anyway.

sorry to hear that, good luck for everything else.
always remember nothing is harder then exam 1 2018 methods!!

The question about statsville and mathsville, where you had to find the probability the proportion of those having a low BPM was greater than 0.99

I got 1/8 
Edit: Just realised you were asking about the last page instead of the second last - ignore me!

All I can say about the exam is this... 
AAAARGH!

damn then  i didnt get that? are you talking about the smallest number of n, for p hat to be greater than 0.99

I got 1/8 

I got 1/8 for the area between the two functions (not the very last question), but not for that question.

Has everyone sat the exam? Or are there still people doing it at a later date?

That wasn’t easy but I feel like it was so much better than last years!

Did anyone else get 41 for the number of trials and what did people get for the very last question?

Everyone has to sit it at the same time. Otherwise there would be risk of cheating.

what did you guys get for the last probability question?
if you cant remember your answer, what was your theory behind it?
